Versiline CUI: Unbeatable protection against corrosion under insulation 

Hempel’s heat-resistant Versiline CUI offers unbeatable protection against corrosion under installation to ensure you benefit from continual uptime and reduced maintenance costs, even in the toughest corrosive conditions.

Corrosion under insulation (CUI) is one of the major challenges facing equipment operators in process industries today. It costs the industry significant lost revenue from downtime, repeated maintenance and replacement of corroded parts.

A fast and effective solution to CUI, Versiline CUI will reduce your overall lifecycle costs and ensure you benefit from continual uptime.

Increased heat resistance and excellent application properties

The excellent heat-resistant properties of Versiline CUI make it extremely resistant to micro cracking, even when subjected to extreme temperatures, from cryogenic (-196ºC) up to 650ºC. In addition, carefully selected barrier pigments make it highly effective against CUI, even under cyclic conditions.

Versiline CUI is suitable for use as long-term protection of hot pipework, equipment and other hot surfaces. It can be used on carbon and various types of austenitic and duplex stainless steels and applied either to hot surfaces on-site, in maintenance situations or to grit-blasted steel for newly constructed pipework and equipment. The hardness and excellent adhesion of Versiline CUI make it especially suited to offsite application.

An MIO-pigmented single-component inorganic copolymer coating, Versiline CUI cures to form an inert polymer matrix. It is able to resist temperatures up to 650°C/1202°F and thermal shock/cycling in dry or dry/wet service conditions.
